The sites here are (mostly) related to physics, but have been chosen largely for fun rather than any direct educational value. If you wish material  related directly to the GCSE course or A level course, then try the appropriate links.

•     Hubble pictures. There are some good pictures here. I particularly recommend “nebulae”  in the "Showcase" option.

•     Big Bang FAQs. Might help with your more bizarre queries.

•     Constellations. A good guide to the constellations, the myths associated with them, and details about some of the more prominent stars in each constellation.

•     Sky map. (Don't load the Windows version of Skyglobe from this site. It's unstable.)

•     Skyglobe. 

Both of these are shareware programs that show position and names of stars, constellations and planets. If you want to know your way around the sky, these would be a good place to start. (I prefer Skyglobe, but that may be through habit.)

•     Physics FAQs. Does antimatter “fall” upwards , and similar questions.

•     How stuff works. Including how to make a nuclear bomb, for the more ambitious.

•     NASA. NASA's main home page. Fancy some really different work experience?

•     Fractint. MAKE SURE YOU GET THE WINDOWS VERSION unless you enjoy playing around in DOS. This is a fractal generator program. My favourite is the Mandelbrot set, especially with the colour changed to blue - have a look here if you want to see what that means. 

•     Bad Physics. Geoff Piper, a teacher at Sutton Valence, takes the opportunity to rant about his "favourite" examples of lousy physics and incompetent language. I'm glad it's not just me.......

•      Colorado university. All sorts of good quantum stuff here - try the "table of contents" to see what's available. Outside the scope of most of the A level course, but well presented and non-mathematical.

•     Lights of Earth. A composite map of all the sources of light on the Earth's surface. A stunning image.

•     Bad movie physics. A pretty comprehensive rant!
